What is the difference between 80186 & 80188 microprocessor?

The Intel 80188 microprocessor was a variant of the Intel 80186. The 80188 had an 8-bit external data bus instead of the 16-bit bus of the 80186; this made it less expensive to connect to peripherals. The 16-bit registers and the one megabyte address range were unchanged, however.

What is the main improvement of the 80186 microprocessor over 8086?

A microprocessor developed by Intel circa 1982. The 80186 was an improvement on the Intel 8086 and Intel 8088. As with the 8086, it had a 16-bit external bus and was also available as the Intel 80188, with an 8-bit external data bus.

What do you know about the modes of 80186?

The 80186 provides eight addressing modes. These include register, immediate, direct, register indirect (SI, DI, BX, or BP), based (BX or BP), indexed (SI or DI), based indexed, and based indexed with displacement modes.

What is microprocessor list its function?

The functions of microprocessor are given below: (a) To fetch, decode and execute instructions. (b) To transfer data from one block to another block or from one block to I/O lines. (c) To give proper response to different externally produced interrupts according to their priority.

What are the differences between a register and a memory location?

Registers are the smallest data holding elements that are built into the processor itself. These are the memory locations that are directly accessible by the processor….Difference between Register and Memory :

S.NO. Register Memory
2. Register holds the small amount of data around 32-bits to 64-bits. Memory of the computer can range from some GB to TB.

What are the main features of Intel 8086?

Features of 8086 It was the first 16-bit processor having 16-bit ALU, 16-bit registers, internal data bus, and 16-bit external data bus resulting in faster processing. It uses two stages of pipelining, i.e. Fetch Stage and Execute Stage, which improves performance.
